Description

Rare decay modes J/ψ→Ds-π++c.c., J/ψ→D-π++c.c., and J/ψ→D-bar0K-bar0+c.c. are searched for using 5.77x107J/ψ events collected with the BESII detector at the BEPC. No signal above background is observed. We present upper limits on the branching fractions of B(J/ψ→Ds-π+)<1.3x10-4, B(J/ψ→D-π+)<7.5x10-5, and B(J/ψ→D-bar0K-bar0)<1.7x10-4 at the 90% confidence level
